Definitions

  • the present invention relates to snap-fit or quick connectors, and more particularly to such connectors which are employed in fluid conduit systems to facilitate connection and disconnection of fluid conduits.
  • Snap-fit or quick connectors have been found to be useful in a wide range of applications. In particular, they are frequently employed for joining fluid carrying conduits in automotive and industrial applications. Such connectors have found general acceptance as they are typically capable of being closed in a single uniaxial movement which facilitates automated assembly, and entail simple designs which are relatively inexpensive to produce. A further advantage of quick connect fittings is that they provide an effective seal for handling volatile or hazardous fluids, such as gasoline, while permitting ease of disassembly and reassembly during repair of a host system. Typically, quick connectors employ a female component or housing which fixedly receives one end of one conduit or tube.
  • a retainer is mounted in the female component and typically includes a pair of deflectable fingers which snap behind a raised annular flange on a male conduit or tube after the male conduit or tube has been fully inserted into the female component.
  • a variety of types of retainers are employed including one which snaps into apertures formed in the female component so as to be actuatable by itself to permit separation of the male and female components.
  • Another type of retainer is housed completely within a female component thereby requiring the use of a special tool to effect release of the quick connector components.
  • One piece, squeeze-to-release quick connectors are also known.
  • a flexible ring is attached by two thin beam members to the open end of the female component.
  • Two deflectable fingers extend from opposed sides of the ring and are disengaged from the annular flange on the male component when opposite portions of the ring are squeezed together.
  • the retainers employed in such quick connectors require specially designed housings as well as a separate retainer component which adds cost and assembly time to the manufacture of the quick connector.
  • the present invention is a one piece quick connector and integral retainer which sealingly locks a male connector and a female connector in a sealed relationship.
  • the quick connector of the present invention includes a housing having a through bore extending from a first end to an opposed second end; and at least one bendable retainer finger integrally formed as a one piece extension of the housing and projecting from the first end of the housing, the at least one retainer finger movable from a first, normal, inoperative position external of the housing to a second position in the through bore in the housing to engage the abutment surface on the male connector upon insertion of the male connector into the through bore in the housing.
  • the at least one retainer finger includes a plurality of circumferentially spaced fingers. Further, the plurality of retainer fingers are arranged in at least one pair of diametrically opposed fingers. Further, and more preferably, a plurality of pairs of diametrically opposed retainer fingers are formed on the housing of the quick connector.
  • a thin, flexible web connects each finger to the end of the housing.
  • the web is positionable at a number of different locations on the first end of the housing, including one position extending axially from the first end of the housing, at another position extending axially from a radially outward extending projection formed on the first end of the housing, or in another position in which the web extends axially from a radially inward extending projection formed at the first end of the housing.
  • each finger with a recess at the end adjacent to the web to provide an edge which is normally spaced from an edge on the radially inward extending projection at the first end of the housing; but is engageable with the edge on the radially inward extending projection whenever axial forces are exerted on the quick connector tending to separate the connector parts.
  • a metal clip means is mountable over the first end of the housing into engagement with an exterior surface of the housing for adding additional pull out resistance by maintaining the deflectable retainer fingers in their inward, angularly extending, latching position in engagement with the annular flange on the male component disposed within the bore in the housing.
  • the housing is made of metal, with the at least one and, preferably, a plurality of retainer fingers normally extending axially from one end of the housing. The fingers are bendable to an angular, inward extending, latching position for engagement with the annular flange the male connector.
  • the retainer is a separate annular band having a plurality of spaced fingers integrally molded on and extending from the band.
  • the band is formed into an annulus and mounted within the bore of a metal connector housing between an internal shoulder in the bore and an in-turned end of the housing.
  • the fingers normally extend axially out of the open first end of the housing, but are deployable to an angular inward extending position to lockingly engage the annular flange on the male connector when the male connector is inserted into the bore in the housing.
  • the retainer is integrally formed as a one piece extension of the connector housing thereby eliminating the need for a separate retainer or a specially designed housing to accommodate the separate retainer as in a large number of previously devised quick connectors. This lowers manufacturing costs of the quick connector while still providing high pull out resistance and a complete seal between two mating connector parts.
  • the integral retainer may also be formed as a one piece extension of a metal connector housing to provide the same functions.
  • the retainer is a separate, molded member, but one including a plurality of normally axially extending, bendable fingers which are deployable from a first position normally extending axially outward from the first end of the housing, to an angularly inward extending position engageable with the annular flange on the male connector.

  • the retainer means 14 is integrally formed as a one piece, continuous part of the female connector part 12. Since the retainer means 14 is integrally formed with the female connector part 12, both the retainer means 14 and the female connector part 12 are formed of the same material. Preferably, a suitable plastic, such as filled Nylon 12, by example only is employed to form the one piece female connector part 12 and retainer means 14. Other suitable materials may also be employed.
  • the retainer means 14 comprises at least one and, preferably, a plurality of fingers 40.
  • the fingers 40 are circumferentially spaced about the open first end 18 of the female connector part 12. Further, the fingers 40 can be provided in any number; although four fingers 40 are shown, by example only, in Fig. 3. Excellent latching capability is provided by an even number of fingers 40 arranged in opposed pairs as shown in Fig. 3. Thus, 2, 4, 6, etc. fingers 40 can provide a sufficient latching capability to the quick connector 10. An odd number of fingers 40 can also be employed, however.
  • the fingers 40 may be provided in different embodiments, as described hereafter, which embodiments vary in the shape of each finger and/or its mounting location on the female connector part 10, all of the fingers, such as fingers 40, share common characteristics such as being integrally connected to the female connector part 12 by a thin web or lining hinge, such as web 42, shown in Figs. 1 and 2. Further, in all of the different embodiments of the fingers, the fingers, such as fingers 40, are initially formed to extend in a general axial direction with respect to a longitudinal axis extending between the first and second ends 18 and 20 of the female connector part 12, as shown in Fig. 2.

  • a characteristic length (L) of each finger 40 between the ends 47 and 48 is greater than the nominal radius (r) of the bore 22 at the open first end 18; but not greater than the diameter of the bore. This enables a juxtaposition of overlap of the outer ends 48 of the fingers 40 when the fingers 40 are folded into the bore 22.
  • the outer ends 48 of the fingers 40 are angled and contoured so as to be substantially parallel to a trailing or axially rear facing surface 31 of the upset or flange 30 on the male connector part 16 when in the folded, locking position for maximum surface contact.
